Urinary Retention: Why the Bladder Cannot Empty Completely

Overview

Urination is an essential function that removes waste and excess fluids from the body. Normally, the bladder fills and empties completely. However, sometimes the bladder may not empty fully or may fail to release urine entirely. This condition is known as urinary retention.

It can occur suddenly or develop over time. While it can affect anyone, it is more common in men, especially with age due to prostate-related issues.
